Freeform drawing with mouse

girig

Hi,

  Is it possible to draw freeform curves/shapes in virtuoso?

If not, any tricks that can make use of multiple piecewise "line" shapes tracking mouse movement?

I was able to get a crude piece of code working through enterPoints, but that can only track clicks, so the user has to click in short bursts close enough to get the desired shape. It would be ideal if a mouse-drag can be used to draw piecewise linear points tracking the cursor - amounting to a free-form shape.

procedure(addPt(win points)

 cv = deGetCellView(win)

 size = length(points)

 if(size>1 then

   pt1 = nthelem(size,points)

   pt2 = nthelem(size-1, points)

   dbCreateLine(cv list("text" "drawing") list(pt1 pt2))

  )

)

enterPoints(?prompts list("Enter Points") ?addPointProc "addPt" )

Thanks !
Giri.

    Giri,

    I don't believe this is possible (at least not with a public API). The "strokes" interface sort of does this, but it doesn't give you access to all the drawn points. This would need an enhancement request - so you'd have to contact customer support with an explanation as to why you need it (it's a slightly unusual request).

    Regards,

    Andrew.
